The complete chloroplast genome of a critically endangered tree species, Hopea reticulata (Dipterocarpaceae)

Abstract

Hopea reticulata Tardieu is a critically endangered tree species distributed in limited regions in Thailand, Vietnam and Hainan Island of China. In this study, we reported the complete chloroplast genome sequence of H. reticulata assembled from pair-end reads generated by Illumina sequencing. The circular chloroplast genome is 151,407 bp in length and comprises a large single copy region of 84,352 bp, a small single copy region of 19,733 bp, and a pair of inverted repeats of 23,661 bp each. The complete genome encodes 129 functional genes, including 83 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The overall GC content of the chloroplast genome was 37.4%. Phylogenetic analysis showed that H. reticulata is sister to H. hainanensis with strong bootstrap support.
